A COMPARATIVE LABORATORY STUDY OF THE CLEANING EFFICIENCY OF XP ENDO FINISHER AND SONIC IRRIGATION [PDF]

Alexandria Dental Journal, 2018
INTRODUCTION: Debridement of the root canal system is essential for endodontic success. Traditional instruments alone cannot sufficiently clean root canals. There must be an effective delivery system. OBJECTIVES: was to compare the cleaning efficiency of

Study on the Reaction Mechanism of RuOx and Its Enhanced Hydrogen Evolution Reaction Activity

Advanced Science, EarlyView.
In situ Raman spectroscopy and DFT calculations reveal that, prior to the onset of HER, the surface of RuOx undergoes reversible reduction and structural reconstruction. The resulting Ru(II)O/Ru(IV)O2 configuration is identified as the true catalytically active species.

Development and Applications of a Magnetism‐Aware General‐Purpose Atomic Cluster Expansion Potential for the Fe‐O‐H Ternary System

Advanced Science, EarlyView.
Hydrogen‐driven iron oxide reduction, water‐iron corrosion, and hydrogen embrittlement of metallic iron share the same Fe‐O‐H chemistry. A general‐purpose Atomic Cluster Expansion potential covers this chemistry across the full concentration range with explicit Ising‐like treatment of magnetism.

The effect of 17% EDTA and MTAD on smear layer removal and on erosion of root canal dentin when used as final rinse: An in vitro SEM study

Journal of International Clinical Dental Research Organization, 2010
Background: The aim of the present study was to evaluate and compare the ability of a mixture of tetracycline isomer, citric acid and detergent (MTAD) and ethylene diamine tetra-acetic acid (EDTA) in removing the smear layer along with their effects on ...

Electric‐Field‐Controlled Interconversion of Antiferromagnetic States in a Two‐Dimensional Antiferroelectric Halide Perovskite

Advanced Science, EarlyView.
Electric‐field‐controlled antiferroelectric switching offers a ferroic pathway for reversible interconversion between symmetry‐distinct antiferromagnetic states in a two‐dimensional halide perovskite. A spin‐split altermagnet transforms into a spin‐degenerate type‐IV antiferromagnet through field‐driven structural symmetry reconstruction, enabling ...

Highly Sensitive Spatial Host‐Microbiome Transcriptomics in FFPE Tissues via Iterative Hydrogel Expansion

Advanced Science, EarlyView.
Ex‐spRandom is a spatial transcriptomics platform that synergizes random‐primed chemistry with iterative hydrogel expansion. By physically decrowding the dense FFPE matrix, this scalable technology shatters the traditional resolution‐sensitivity barrier.

Comparison of new irrigating solutions on smear layer removal and calcium ions chelation from the root canal: An in vitro study

Endodontology, 2018
Background: The action of endodontic instruments leads to the formation of smear layer during biomechanical preparation. Smear layer removal not only enhances the three-dimensional sealing of the root canal system but also improves the dentinal tubule ...

Bidirectional Soft Catalysts for Improved Power Performance of Li‐S Batteries

Advanced Science, EarlyView.
A soft polymer‐metal catalyst is integrated into the binder to create a catalytically active microenvironment that accelerates bidirectional sulfur redox kinetics in lithium‐sulfur batteries. A model polyvinyl alcohol‐Cu catalyst enables high areal capacities at demanding current densities and stable cycling in pouch‐cell prototypes at 0.5 C, achieving
